Licensing

Cello Package Management is an effective SaaS based packaging solution, enabling ISVs to package multiple modules and features into a single accessible threshold, based Licenses or Plans.

Example

  • ISVs can create Licenses like Basic, Premium, Package1, Package 2 etc and make it available for the customers to subscribe
  • As part of the security framework, Cello validates the type of the license subscribed and its modules and features in the given license, and blocks the usage of unsubscribed Features

Metering

Active Monitoring of the actual usage of the solution in real-time and enforces the license limits. Administrators can set variety of metering threshold, based on the configuration the framework keeps track of the usage by the end users,once the user reach the threshold, the feature can either be made unavailable or blocked.

Cello supports two types of metering, such as prepaid i.e. decrement metering and post paid i.e. incremental metering, based on the requirement you will be able to do both of the options, and you have the control of incrementing or decrementing numbers i.e. 1 usage per transactions or 2.

Example

  • when 100s products assigned for a basic package, customers who subscribe to the basic package can access/create to only up to 100; similarly when 1000 numbers assigned to the premium package, customers will be able to access/create up to 1000 products; if you would like to assign unlimited usage, then set 0 to provide unlimited usage

Billing

Dynamic Data Scope

Dynamic Datascope offers data level privilege management. Administrators can set data entitlement as to whether a user can access a specific record or specific columns in the particular entity.

Once set, these data level access privileges will be validated in the procedural code and granted access to view or edit the data based on the privilege the user holds.

Example

  • A manager can see only his subordinate details or department details. A sales person can see only data related to his territory
  • Only HR group can see the salary details of all the employees
